Li qub muaj ntau hom kev sib txuas, suav nrog flanges, wafers, taub qab welds, xov, ferrules, thiab clamps. Cov kev sib txuas no sawv cev rau kev sib txuas ntawm lub pob valve thiab raj xa dej lossis khoom siv. Kev xaiv ntawm valve txuas hom yog cuam tshuam los ntawm ntau yam thiab tsis tuaj yeem xaiv kev sib nyiam. Qhov teeb meem no tsis tuaj yeem tsis quav ntsej, raws li feem ntau ntawm valve xau, bubbling, dripping, thiab to qhov tshwm sim ntawm no.
Flanges yog qhov kev sib txuas ntau tshaj plaws uas siv hauv li qub thiab tuaj yeem raug cov qauv ntawm cov chaw mating raws li hauv qab no:
1. Tus du: Siv rau cov li qub nrog cov khoom siv tsis yooj yim thiab yooj yim rau lub tshuab.
2. Convave -} convey convey thiab tsim nyog rau nruab nrab- tawv gaskets.
3. Tus nplaig -} thiab-} Groove: Siv rau cov gaskets nrog kev ua yeeb yam zoo nkauj, thiab muab cov khoom sib khi ua kom zoo.
4. Trapezoidal Groove: siv ib lub nplhaib hlau nplaum elliptical li lub gasket thiab yog siv rau kev ua haujlwm ntau dua lossis sib npaug lossis siab- kub li qub.
5. Lens: lub gasket yog lens - zoo li cov hlau. Siv rau high - h siab} Kev ua haujlwm ntau dua lossis muaj sib npaug rau 100 kg / cm / cm /- kub li qub.
6. O {{{{{{{1} lub nplhaib: Qhov no yog qhov kev sib txuas Flange tshiab, tsim nrog kev tawm tsam ntau yam roj hmab o- rings. Nws muaj ntau dua kev sib tw ua tau zoo dua li cov gaskets.
Threaded kev sib txuas yog qhov kev sib txuas yooj yim, feem ntau siv rau cov li qub me, tab sis yog categorized ua ob hom:
1. Ncaj nraim ncaj qha: cov xov sab hauv thiab sab nraud ncaj qha ua raws li cov hlua. Txhawm rau kom pom tseeb qhov xau - Pov thawj, ua roj, hemp, thiab PTFE daim kab xev feem ntau siv. PTFE daim kab xev yog ua kom nrov dua. Cov ntaub ntawv no muaj kev tiv thaiv corrosion zoo heev, muaj cov nyhuv zoo tshaj, thiab yog yooj yim siv thiab khaws cia. Nws tuaj yeem tshem tawm mus dhau thaum lub sij hawm disassembly vim tias nws ua ib qho tsis - cov yeeb yaj kiab, ua kom zoo dua li txhuas cov roj thiab hemp.
2. Indirect sealing: Lub zog los ntawm zawm cov xov pauv mus rau lub gasket ntawm ob qhov chaw, cia lub gasket kom ua cov haujlwm sib khi.
Qhov kev sib txuas thiab cov cai sib txuas ntawm kev sib txuas ntawm ferrule yog tias thaum cov txiv ntoo tau ua kom nruj, ua rau nws txiav rau hauv phab ntsa sab nraud. Lub sab nraud ntawm lub ferrule ces ntsaws ruaj ruaj rau sab hauv ntawm lub siab, yog li tiv thaiv xau.
Qhov zoo ntawm cov kev txuas no yog:
1) Qhov loj me me, lub teeb yuag, cov qauv yooj yim, thiab yooj yim los ua ke thiab disassembly;
2) Muaj zog sib txuas lub zog, thiab kev tawm tsam dav ntau yam, thiab kev tawm tsam rau kev kub siab (1000 kg / cm / cm / cm2), Kub (650 degree), thiab surration thiab poob siab;
3) muaj ntau cov ntaub ntawv tuaj yeem siv, ua rau nws haum rau corrosion tsis kam;
4) Tsawg dawb software precision yuav tsum muaj;
5) yooj yim rau high-} ceg nruab nrab.
Lwm qhov kev sib txuas yog qhov kev sib txuas ntawm kev sib txuas, uas ncaj qha rau lub valve thiab ob tus yeeb nkab xaus ua ke siv bolts. Muaj ntau ntau lwm yam valve kev xaiv, xws li cov li qub me uas tsis tas yuav muaj kev rhuav tshem thiab yog welded rau yeeb nkab; Thiab qee qhov tsis - nws yog xim hlau siv ntswj -} spigot sib koom tes.
